A voting machine filmed by a voter in Pennsylvania appears to show votes being changed from the intended candidate.

The video, featured above, shows a voter trying to select “Barack Obama” but instead the machine selects “Mitt Romney.”

“I initially selected Obama but Romney was highlighted. I assumed it was being picky so I deselected Romney and tried Obama again, this time more carefully, and still got Romney,” the uploader wrote on their YouTube page, which was only registered today.

“Being a software developer, I immediately went into troubleshoot mode. I first thought the calibration was off and tried selecting Jill Stein to actually highlight Obama. Nope. Jill Stein was selected just fine. Next I deselected her and started at the top of Romney’s name and started tapping very closely together to find the ‘active areas’.”

Eventually, the anonymous voter found the portion of the touch screen that would allow them to vote for Obama.

“From the top of Romney’s button down to the bottom of the black checkbox beside Obama’s name was all active for Romney. From the bottom of that same checkbox to the bottom of the Obama button (basically a small white sliver) is what let me choose Obama.”

The YouTube page is anonymous and no contact information is listed for the voter, so it is not possible to verify the content of the video. The user has been messaged through YouTube’s internal system and we are now awaiting reply to verify the content of the video with the uploader.

As this related video from the 2008 election shows, though, it’s possible that the voting machine in question could just require calibrating, the equivalent of hitting the “Reset” button on your home computer when it starts acting up (h/t @gilmourtaylor).
